Letters Patent N 102,604, dated May 3, 1870; alitedated April 29, 1870.

IMPRovED Sissa-HOLDER.

The Schedulepreferred to in these Letters Patent and making part of 'che same.

To all whom it may concern Be it known that I, It. L. SIBBET, M. D., ot' New Kingston, in the' county of Cumberland and Stat-e of Pennsylvania, have invented a new and useful Improvement in 1WindowfSash Fastener; and that the following description, taken in connection with the accompanying plate of drawings,'hereinafter referred to, forms a full and exact specification' of the same, wherein I have set forth the natureand principles ot' my said improvement, by which my invention may be distinguished from others of asimilar class, together with such parts as I claim and de'sire to secureby Letters Patent.

My invention relates to that class of window-sash fasteners in which the bolt, arranged with a spring, is operated by a knob or crank, and consists iu arranging a dat spring, attached tov the outside of the frame, with the bolt or catch, as hereinafter described.

1u the accompanying plate of drawings, which illustrate my invention, and form a part ot' the specification thereof Figure l is a section ot' the common form of wiudow-trame, with my invention applied thereto. .l

Figure 2 is a section of the common form of window-sash, with slots for the reception of a bolt.

Figures 3 and 4 illustrate the inode of securing the hook-bolt upon the spindle. i

Figure 5 shows a form of bolt which may he used for the purpose of locking the sash. Y

My invention is constructed and applied as follows, to wit:

Upon two of the sides of the spindle A a thread is cut, and upon the end thereof is secured the knob B. lEhe said knob may be made solid with the said spindle, orattached to the same by means of a screw. The latter method would be preferable in the adaptation of my inventiouto car-windows Upon the lower end of the shank f the hook O is cut an oblong slot, of such a size` and shape that the said hook may be adjusted upon the attened screw of the spindle A, in any desirable position, by means ofthe nuts D, whose internal threads 'correspond with and it the external thread cut upon the spindle A.

A cylindrical perforation, represented by dotted lines in tig. 1, is made in the frame E, of such a caliber as to admit of the introduction ot' the spindle aforesaid,

and constitute a journal in which the same may be revolved. l

Slots are cut .in the frame, at D, of such a contiguration as to conform to the shape of the hooks C and nuts D, and admit of the operation'of the same.

The plate springs G are screwed to the frame, and are provided with rectangular notches, H, which lit over the shoulders I of the hooks G, hold the same in position, and shoot. the bolt end of the said hooks.

Upon the sides of the window-sash are cut the slots K, for the reception of the bolts aforesaid.

Having thus described the construction and component parts ot' my invention, I will proceed to indicate its operation.

The spindle A having been placed in the journal prepared for its reception, the hook C is passed over the end thereof, and secured in position by the nuts D, which may be turned while in the mortise by means of a small wrench or other instrument adapted to the'purpose. The shoulders ot` the bolt I are then secured by the spring G, and' the said spring is screwed rrnly to the frame.

The bolt end L may be so constructed as to lock the sash, so that it cannot be moved by extraneous force, by causing the said bolt to curve slightly d ownward, as represented iu fig. 5,.and cutting notches thereon; or it may be so constructed as to allow the sash to bel raised, without applying force to the knob B, by upward pressure of the said sash. l

I am aware that hooks attached to spindles passing transversely through the window-frame have been heretofore patented, (see patent of A. Bradford, December 15, 1868.) I am also aware that springs have long been used for the purpose of operating sash-fasteners.

I therefore liinit myself as to what I claim as new,

and desire to secure by Letters Patent, as follows, to

wit: v

The at spring G, with its notch H, when arranged to operate wit-h the hook @substantially as herein described.
